Manganese Extra Heavy Duty AA size 4pcs value pack UM-3SHD/4BVP

Safe, Eco-Friendly Manganese Power

The difference between Panasonic and conventional manganese batteries is clear. Advanced design and materials selection, better production techniques and more stringent quality control result in superior safety and performance, even after many years in storage. And unlike many other brands, our eco-friendly manganese cells do not contain the three major specified toxic substances. That's a huge benefit for keeping the environment pollutant free.

Now with Zero Lead Added

An Advanced Approach to Protecting You and the Environment

Panasonic released its first mercury-free battery back in 1991. Now it is among the first in the world to eliminate lead from its design. Our manganese battery family does not contain lead, cadmium or mercury. This not only protects you as you are using the product, it also protects the environment after battery disposal.

New and Specialized Zinc-Alloy Can

An Advanced Approach to Protecting You and the Environment

Our manganese battery series overcomes traditional engineering challenges to successfully combine advanced technology and high quality with low cost. A key feature is the new zinc-alloy can, which is not only stronger than conventional cans, but much more resistant to corrosion as well.

Industry-leading Anti-leak Protection

Improved Leakage Resistance for Safety

We protect the people, equipment and moments that are important to you with the industry’s most advanced leak protection technology. While gas buildup is a primary cause of rupture and leakage in alkaline batteries, it is the structural weaknesses in conventional manganese cells that cause the most problems. Panasonic answers these tough engineering challenges with an extremely robust design that incorporates a stronger collector rod sealing structure, nylon inner tube protection and a metallic outer can.
